Ashwagandha Herb Extract
Also known as: Ashwagandha, Indian ginseng, Winter cherry, Withania somnifera
Overview
Ashwagandha (*Withania somnifera*) is an adaptogenic herb widely recognized for its stress-reducing and health-enhancing properties. Originating from India and Africa, it has a long history of use in Ayurvedic medicine. Ashwagandha is primarily used to manage stress, improve sleep quality, and enhance physical performance. It is available in various forms, including capsules and powders, derived from the plant's roots and leaves. Research indicates that Ashwagandha may help modulate cortisol levels and influence neurotransmitter activity, contributing to its adaptogenic effects. While research support is growing, the quality of evidence varies, necessitating careful evaluation of study designs and outcomes. Overall, Ashwagandha is considered a promising natural supplement with a range of potential benefits, particularly for stress and sleep-related issues.
Benefits
Ashwagandha has demonstrated benefits in improving sleep quality and reducing anxiety. A meta-analysis indicated a small but significant improvement in overall sleep quality (SMD -0.59; 95% CI -0.75 to -0.42). It is particularly effective for individuals with insomnia when using doses of 600 mg/day or more for at least 8 weeks. Secondary benefits include stress reduction and potential improvements in physical performance, although these effects are less consistently documented. Studies also suggest that Ashwagandha can enhance mental alertness and cognitive function. The herb's adaptogenic properties help the body manage stress by modulating the hypothalamic-pituitary-adrenal (HPA) axis.
How it works
Ashwagandha primarily functions by interacting with the body's stress response system. It is believed to modulate cortisol levels, reducing the physiological impact of stress. The active compounds, such as withanolides, may interact with GABA receptors and other neurotransmitter systems, influencing mood and anxiety. Ashwagandha affects both the nervous and endocrine systems, contributing to its adaptogenic properties. While the exact mechanisms are still under investigation, it is understood that Ashwagandha helps the body maintain homeostasis under stressful conditions, promoting overall well-being.
Side effects
Ashwagandha is generally considered safe, but it can cause side effects in some individuals. Common side effects include gastrointestinal upset and drowsiness. Less common side effects may include allergic reactions and increased heart rate. Due to its potential effects on hormone levels, caution is advised for individuals with thyroid disorders or those taking thyroid medications. Ashwagandha may also interact with sedatives, blood thinners, and medications for diabetes or blood pressure. It is contraindicated in pregnancy, breastfeeding, and individuals with autoimmune diseases. Rare side effects are not well-documented, but it is essential to monitor for any adverse reactions when starting Ashwagandha supplementation.
Dosage
The minimum effective dose of Ashwagandha is generally considered to be 300 mg/day. For sleep and stress benefits, a dosage of 600 mg/day is often recommended. Dosages should typically not exceed 1000 mg/day without medical supervision. It is best taken with meals to reduce the risk of gastrointestinal side effects. Ashwagandha is commonly available in capsule or powder form. While specific absorption factors are not well-documented, consuming it with fatty meals may enhance bioavailability. Start with a low dose and gradually increase as needed to assess tolerance and effectiveness.
